I saw it portrayed in a movie , but until I touch the Ark myself , I will still have doubts . Until I get to go to work by alien entrepeneur provided saucer , my similar doubts will not be lifted. Until it is a reliable entity in our daily lives , ZPE will face these doubts . We may find that the only viable use for ZPE is it's already mega-magnificent use as the sub-space support for the ground-state of atoms which underlies all of what we call the universe. That is in itself , big. I remember seeing a picture of an atom on the web and the caption read ,'The fuzz you see to the outside of the atom is the cloud of virtual photons that surrounds all atoms' . There lies ZPE , or at least one example of it (Yes, the web has pictures of ZPE).
